Kev,
If the sound seems to be "deep in the block" you'd almost certainly hear it louder in the rear part of the oil pan, which would act like a resonator, plus would be the thinnest and least oil-insulated place for the sound to escape.
I really would concur that a mechanic's stethoscope would be very helpful with a problem like this. It's a good investment for pinpointing all kinds of clicks, rattles, squeaks and things that go bump in the night.
My first guess would be a valve train problem, even though the sound seems "deeper." Scope near each valve assembly. Could be a spring or a keeper, or of course a lifter.
With all due respect, the valve train looks in need of some attention. I've found that many problems can be located by simply cleaning and inspecting carefully.
I'm still a bit afraid the culprit might be a ring. The tranny fluid cure can clean things up and unstick them, but if you've got a broken one, it won't fix it.
Be sure to don your scrubs and gauze mask while using the stethoscope. That's how mechanics can charge extra when they use one.
